We propose a technique to reduce false positive detections made by aneural network using an SVM classifier trained with features derived from theuncertainty map of the neural network prediction . We demonstrate the effectiveness of this method for the detection of liver lesions on a dataset ofabdominal MR images . We find that the use of a dropout rate of 0.5 produces the least number of false positives in neural network predictions and thetrained classifier filters out approximately 90% of these false positivesdetections in the test-set .
